Crafty aren't Wizard or White Wolf. They don't have lots of money and writers to throw at a problem. At the moment it's just 2 writers, an artist and a bunch of freelancers, and it isn't the primary source of income for any of them - it's a second job.
In all fairness, 2.0 has been out for nearly 5 years now. I think other companies would have slapped us with a new edition before then. There was only a 3 year gap between D&D 3e and 3.5, and then a similar 5 year gap between 3.5 and 4e.
You sir, have squarely hit upon my issue. I'm aware of Crafty's size & I don't expect them to be WotC, White Wolf, or even Paizo. This is the primary source of my concern -- they're circling back to the espionage genre with a new edition -- meaning fewer resources or longer wait times for other genre products.
I didn't realize it had been 5 years since 2.0's release. Comparing FC & SC I can see how their game design has evolved and while I don't think there aren't benefits to be gained in a new SC edition, I don't know that it'd be at the top of my wish list. That's just me and my personal tastes, obviously.
Obviously, the ideal scenario would be for Crafty to continue to prosper and be able to bring in other writers, etc. to produce more products in shorter timeframes. I WANT that to happen and if it does, great.
Until then, however, it all comes down to resource allocation. I get it. They can't be all things to all people.
However, there's nothing wrong with me wanting to have a single RPG framework (i.e. MasterCraft) to be the RPG engine for ALL of my RPG needs. Color me crazy for wanting to see that happen before my kids go off to college. All too often in the RPG industry, a line goes about 50% of the way it was conceived before the "new edition" reinvention of the wheel occurs. Sometimes, like with SC & FC, the wheel rocks on toast. Sometimes (sorry 4e, I'm looking at you), it's now octagon-shaped.
Ultimately, business realities drive the lines & development, or lack thereof. So here's what I'm saying to Crafty:
1) I plan to continue to purchase FC expansions.
2) I'll pick up 10k Bullets.
3) I'll stay tuned to SC 3.0 and may pick it up.
4) I'm VERY interested in seeing what Crafty can do with other genres as well.
